# The dpdkstat plugin
+This plugin is optional and only has a specific use case: monitoring DPDK applications
+that don't expose stats in any other way than the DPDK xstats API.
+
**Data Plane Development Kit** (DPDK) is a set of drivers and libraries for fast
-packet processing.
+packet processing. Please note that this plugin is a polling based plugin rather
+than an events based plugin (using it will drive up core utilization on a system).
+
+**PLEASE DO NOT USE THIS PLUGIN FOR OVS-DPDK**. dpdkstat is really for DPDK
+applications that have no other way of exposing stats. For OVS or OVS-with-DPDK the
+Open vSwitch plugins available in collectd 5.8.0 should be used for
+collecting stats and events. In addition the OVS plugin is events based rather
+than polling based and will have a smaller footprint on the system.

+ *
+ * __ENDIAN_LITTLE__ if BYTE_ORDER == LITTLE_ENDIAN then this

+ *
+ * The implementation provides a uniform interface to endian macros using only

+ systems.
+ *
+ * This approach is intended to avoid the need for preflight configure
+ scripts.
+ * An alternative approach would be to test compiler CPU architecture marcros.
+ *
+ * This header has had *limited* testing on recent C11/C++11 compilers and is
+ * based on the austin bug tracker interface, manpages, and headers present in
+ * Linux, FreeBSD, Windows, Solaris and Darwin.
+ *
+ * The header uses __builtin_bswapXX intrinsic with GCC/Clang (__GNUC__) on
+ * platforms that do not provide bswap16, bswap32, bswap64 (Darwin)
+ *
+ * Public Domain.
